A mix of fragmented sensory info to create reality
Info is provided by the environment because of high levels of adaptation.
focuses on the relationship between physical characteristics, and environmental stimuli.
Stimuli that ate to week or brief to be perceived.
Stimuli that are strong enough to be perceived.
ability to detect stimulus
internal rule a person uses to decide whether or no to report a stimulus
a mathematical model of what determines a person's report of whether or not a stimulus has occurred.
the smallest detectable difference in stimulus energy is a constant fraction of the intensity of the stimulus.
smallest detectable change in stimuli
the task of determining what edges and other stimulus go together to form an object
auditory scene analysis
the perceptual process through which sounds are mentally represented and interpreted.
ability to perceive distance
depth cue whereby closer objects block one's view of things farther away.
a depth cue whereby larger objects are perceived as closer than smaller ones
height of visual field
a depth cue whereby objects higher in the visual field are perceived as more distant.
a gradual change on the texture or grain of the visual field, whereby objects with finer, less detailed textures are perceived as more distant.
a depth cue whereby objects closer to the point at which two lines appear to converge are perceived as being at a greater distance.
a depth cue whereby a difference in the apparent rate of movement to different objects provides information about the relative distance to those objects.
the ability of a lens of the eye to change its shape and bend light rays so that objects are in focus.
a depth cue involving the rotation of the eyes to project the image of an object on each retina.
a depth cue based on the difference between two retinal images of the world.
a motion cue involving a rapid expansion in the size of an image so that it fills the available space on the retina.
an illusion in which lights or images flashed in rapid succession are perceived as moving
the perception of objects as a constant in size, shape, color, and other properties despite changes in their retinal image.
Aspects of recognition that are guided by higher-level cognitive processes and psychological factors such as expectations.
Aspects of recognition that depend first on the information about the stimulus that comes to the brain from the sensory receptors.
Mental representations of what we know, and have come to expect, about the world.
parallel distributed processing models
an approach to understanding object recognition in which various elements of the object are thought to be simultaneously analyzed by a number of widely distributed, bu connected, neural units in the brain.
the process of directing and focusing psychological resources to enhance perception, performance, and mental experience.
